Iron Maiden and Metallica will headline Britain's Sonisphere Festival when it returns after a two year break next year (14).

In 2012, the event was cancelled and the 2013 concert was pulled due to a failure to attract big name headliners, but it's back with a vengeance for a big show at Knebworth Park in England in July (14).

Announcing details of the hot ticket gig on Monday (02Dec13), Iron Maiden singer Bruce DICkinson said, "We all grew up in England well aware of the importance of the legendary concerts at Knebworth, and scarily it all seems quite recent!

"Without being cliched, it really is an honour and privilege to return to play there with the purpose of celebrating some of the finest moments in British rock history from inspirational bands like Pink Floyd, The Who, Zeppelin, The Stones and Genesis."

DICkinson also announced that the Sonisphere Festival will be the band's last concert of its current Maiden England Tour.

He adds, "If you are there on the day it is highly likely that you will hear some of these songs played live for the very last time ever. So on an occasion like this, a celebration and the end of a chapter, you can be sure we will do our utmost to give our fans one hell of a show and go out with all guns blazing."
